From c4293333982e9303699dab25140b2d63dfc9a179 Mon Sep 17 00:00:00 2001 From: Xiaojuan Yang Date: Mon, 6 Jun 2022 20:43:32 +0800 Subject: [PATCH] tests/tcg/loongarch64: Add hello/memory test in loongarch64 system - We write a very minimal softmmu harness. - This is a very simple smoke test with no need to run a full Linux/kernel. - The Makefile.softmmu-target record the rule to run.
